In speed control mode, you can set the speed instruction, deceleration time, in order to smoothly to start and stop
the servo motor.
◢
Ta: acceleration time: from 0 r/min to rated speed. For
example, servo motor rated speed 3000 r/min, if the setting time is 3 s, accelerate from 0 r/min to 1000
r/min for 1 s.
Td:
Deceleration time: by the rated speed reduced to 0 r/min
